Individual bits in RAM are toggled by feeding the outputs
of the 74LS189 back to the inputs through a 74HC86.
Since an XOR gate can act like a conditional inverter,
pins 2, 5, 10, and 13 of the '86 are the "control" inputs.
When a "control" pin is high, the '189's corresponding output bit,
which is already inverted, is inverted again, and the bit is unchanged.
When a "control" pin is low, the '189's corresponding output bit
is allowed to pass through unmodified, and the bit's inverse is written
into RAM.

The 4052 multiplexer pulls the "control" line for the selected channel low,
all the others are held high by pullup resistors.

Based on one datasheet, it looks like the 74LS189 has output buffers
to ensure that the \_Qn\_ lines retain their old value during a write cycle.
I verified this with a logic analyzer as well.

This ensures the first beat is not
